In the news lately there has been coverage of material that contain bisphenol A and its use in some dental materials.
I would like to keep you up to date with the current information:
-
- Dental material with bis-GMA and or bis-DMA may contain trace amounts of BPA.
- Materials containing bis-DMA can break down into BPA after coming in contact with Saliva.
- Most FDA approved dental materials are made with bis-GMA, which do not undergo this reaction.
- At Dakota dental in Apple Valley we use materials with bis-GMA.
Dental material are far less likely to cause BPA exposure than other goods such as plastic bottles and metal cans. - The one time-exposure to BPA from dental sealants is about 200 times lower than the daily level EPA considers safe.
- After the sealant or resin is cured, the layer that may contain the BPA can be washed off and suctioned up, or wiped away with a cotton pellet.
- I have sealants and composite dental fillings myself.
These are just a few highlights of the information, if you would like more you can visit ADA.org for greater detail.
Feel free to contact us for more information.
